Day 3 of protests outside the home of disgraced former Minnesota cop Derek Chauvin turned violent as cops in riot gear lined the streets keeping protesters at bay.

For most of the day there was a steady stream of about 150 protesters outside the former cop's home.

Minutes later another Michael Kjnaas, 25, approached the police barricade and another shot a paint ball, also hitting him in the groin.

He dropped to the ground in pain. Several other protesters helped him get up and away from the police.

'The facts that I've seen, which are minimal, certainly lead me down the path that race was involved.'

Minnesota Governor Tim Walz activated the National Guard to the city and state troopers have been called in as it braces for another night of violence.

It came  as prosecutors warned Thursday there is ‘evidence that does not support criminal charges’ in the cas
